The first thing that stands out in these headsets is the deep bass that does not cover the medium sounds. Also, the headsets isolate the user from the outside noise.
The Bluetooth connectivity is stable even in the presence of other Bluetooth devices, the smartphone must be positioned on the same side with the left headset where the Bluetooth antenna is located.
The call quality in the case of these headsets is very good, the microphone would have been preferable to have more volume, which is the only downside of it.

Final thoughts

Due to their ergonomic shape and the good sound quality, the Sacool Pro headsets proves its usefulness at an acceptable price. In terms of appearance, the headsets stand out from the crowd due to their elegant & minimalist design.
The only downside of this product is the volume of the microphone that could be higher.
